This is a task for practicing class-based programming. The task is to create an address book system that can store and manage contact information.
The system should consist of the following classes:
- Field: A base class for record fields.
- Name: A class for storing a contact's name. This field is mandatory.
- Phone: A class for storing a phone number. It should have validation logic to ensure the number is in the correct format (10 digits).
- Record: A class for storing information about a contact, including their name and a list of phone numbers.
- AddressBook: A class for storing and managing records.
-
AddressBook:
- Add records
- Search records by name
- Delete records by name
-
Record:
- Add phone numbers
- Remove phone numbers
- Edit phone numbers
- Search for phone numbers
You can start with the following basic code:
from collections import UserDict
class Field:
def __init__(self, value):
self.value = value
def __str__(self):
return str(self.value)
class Name(Field):
# Implement class logic
pass
class Phone(Field):
# Implement class logic
pass
class Record:
def __init__(self, name):
self.name = Name(name)
self.phones = []
# Implement class logic
def __str__(self):
return f"Contact name: {self.name.value}, phones: {'; '.join(p.value for p in self.phones)}"
class AddressBook(UserDict):
# Implement class logic
passOnce implemented, your code should run as follows:
# Create a new address book
book = AddressBook()
# Create a record for John
john_record = Record("John")
john_record.add_phone("1234567890")
john_record.add_phone("5555555555")
# Add John's record to the address book
book.add_record(john_record)
# Create and add a new record for Jane
jane_record = Record("Jane")
jane_record.add_phone("9876543210")
book.add_record(jane_record)
# Print all records in the book
for name, record in book.data.items():
print(record)
# Find and edit John's phone number
john = book.find("John")
john.edit_phone("1234567890", "1112223333")
print(john) # Output: Contact name: John, phones: 1112223333; 5555555555
# Search for a specific phone number in John's record
found_phone = john.find_phone("5555555555")
print(f"{john.name}: {found_phone}") # Output: 5555555555
# Delete Jane's record
book.delete("Jane")
